WEFT-REPLENISHING MECHANISM FOR LOOIVIS.

SPECIFICATION forming part of Letters 1- mtent No. 788,356, dated April25, 1905. Application filed March 24,1902. Serial No. 99,578.

To all whom, it may concern.-

Be it known that I, HENRY I. HARRIMAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a certain new and useful Improvement in \Veft-ReplenishingMechanism for Looms, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention has relation to the class of mechanisms which have beendevised for the purpose of effecting automatically replenishment of theworking weft-supply of looms when necessity arises therefor--as, forexample, on exhaustion of the supply of weft or filling that is carriedby the working shuttle on the lay of a loom, or on exhaustion thereof toa predetermined extent, or on loss of continuity of such weft orfilling-the action of the replenishing instrumentalities being broughtabout or instituted through the agency of suitable forms ofweft-indicator mechanism. In some types of mechanisms of the said classthe replenishment is effected by discharging or removing the spent orfailed working shuttle from the lay and bringing a fresh or reserveshuttle into action in lieu thereof. In others it is effected byemploying filling-cases adapted for removable application to the bodyofa loom-shuttle, each filling-case carrying a load of weft or filling,and by ejecting the spent or failed filling-case from the workingshuttle on the lay and introducing in its place a reserve filling-caseloaded with weft or filling. In others still it is effected by replacingautomatically the bobbin which is contained within the working shuttleon the lay by a reserve bobbin loaded with weft or filling.

My present improvements are in part applicable to mechanisms in generalof the automatic weft-replenishing class and in part are more especiallyapplicable to mechanisms ofthe types in whichweft replenishment iseffected by automatically replacing the fillingcase or bobbin in theworking shuttle on the lay by a reserve filling case or bobbin.

For convenience l have in the accompanying drawings illustrated mypresent improvements embodied in mechanism constructed and operating toeffect replenishment by making change of filling-cases, and I will thusdescribe the same.

In the drawings, Figure 1, Sheet 1, shows, mainly in side elevation, butpartly in vertical section, a portion of a loom having the saidembodiment of my improvements applied thereto. Fig. 2, Sheet 2, shows infront elevation a portion of the said loom and also represents in dottedlines a portion of a filling-case receiver located adjacent the loom.Fig. 3, Sheet 3, shows, mainlyin plan, a portion of the said loom, themagazine for filling-cases and part of the loom-frame being removed.Fig. 4, Sheet 4, shows in side elevation, and Fig. 5, same sheet, showsin plan, with part thereof broken away, a shuttle suchas is employed inthe loom of Figs. 1, 2, and 3. Fig. 6, Sheet 4, is a view in verticalsection on the plane indicated by the dotted line 6 6 in Fig. 4. Figs. 7and 8, Sheet 4, are views of one of the arrangements which are appliedto the shuttle-body for the purpose of holding the fillingcase in placewithin the chamber or cavity thereof. Fig. 9, Sheet 4, shows in frontelevation, and Fig. 10, same sheet, shows in plan, one of thefilling-cases which are employed in connection with the shuttle of Figs.4 and 5. Fig. 11, Sheet 4, shows the said filling-case in verticalsection on the plane indicated by the dotted line 11 11 in Fig. 9. Fig.12, Sheet 1, is a sectional detail showing partly the positioner and itsoperation. Fig. 13, Sheet 1, shows the cam for operating thefilling-case positioner. Fig. 14, Sheet 3, is a plan of certain details,showing partly the shuttle-box at the change end of the loom, the guidesover is combined. Fig. 16, Sheet 5, is a partly-sectional view of thesame looking at the change end of the loom. Fig. 17, Sheet 5, is an endelevation showing chiefly the knocking-off arrangements. Figs. 18 and19, Sheet 6, are views corresponding. respectively,with Figs. 16 and 17,respectively, but showing the parts in the positions which they assumewhen there is an absence of reserve filling at the detector. Fig. 20,Sheet 7, is a perspective of the details of the picking arrangement.Fig. 21, Sheet 7, is aperspective of some of the parts which are shownin Fig. 20, but representing them as disengaged in order to effectuatethe suspension of the picking. Fig. 22, Sheet 8, is a perspective of aslightly-modified picking arrangement. Fig. 23, Sheet 9, shows the samedisengaged to occasion the suspension of the picking. Fig. 24, Sheet 9,is a detail View showing a modification in which thefilling-case-supporting guides are attached to the front of thelay-beam.

Having reference to the drawings, a a designate the opposite end framesof a loom, and a the breast-beam thereof.

b is the lay-beam, and I) 1/ are the lay-swords, the latter beingpivoted at b and the lay bein g operatively connected with thecrank-shaft c by lay-pitmen I) Z), extending from the layswords I) Z) tothe cranks c 0 of the crankshaft 0, as usual.

(Z is the cam-shaft of the loom.

The shuttle-box back at the change end of the lay-beam is designated 6,the shuttle-box front being designated f, and g is the correspondingpicker-stick, g being the lug-strap through which motion is transmittedto the said picker-stick from the arm g of the adjacent pickingrock-shaft 9 the latter being journaled, as usual, in bearings at g g,which are applied to the corresponding end frame a of the loom, and, asshown in Fig. 2, being furnished with an inwardly-extending arm gprovided with a cone-shaped bowl g, that is acted upon by apicking-tappet g on the camshaft (Z.

it is the rear cross-girth.

It is not material to the invention which form or arrangement ofweft-indicator devices or mechanism is employed in connection with thepresent improvements. Various forms and arrangements of such devices ormechanism are known, some thereof being operative to ascertain breakageor exhaustion of the weft-supply in process of being woven in and othersthereof being operative when the weft-supply within the working shuttleon the lay becomes reduced in quantity to the predetermined minimumprior to complete exhaustion thereof. For convenience of illustration lhave represented in the drawings (see more especially Fig. 3) anordinary Weftfork it, which, as usual, is pivotally mounted upon aweft-fork slide 71,, fitted between guides at [L /I upon the breastbeam. The weft-fork slide It is arranged, as in similar constructions,to press forward the adjacent armz' when said slide is slid forwardacross the breast-beam g in consequence of the engagement of thegooseneck (not shown) with the tail of the weft-work h, as in case ofabsence of the weft or filling from in front of the tines of theweft-fork when the lay beats up. The arm 2' is mounted upon the usualrod 21', the said rod extending across the loom just below thebreast-beam and being journaled in the opposite end frames a a. The rod2" controls the starting of the weft-replenishing instrumentalities,and, as presently will be made to appear in the further description ofthe illustrated embodiment of the invention, when the said rod '21 isrocked, as in consequence of an advance of the weft-fork slide it, thesaid instrumentalities are brought into actionand caused to effectuatethe desired weft replenishment.

I have represented the parts which are more immediately concerned in theperformance of the weft-replenishing operations as actuated by cams upona change-shaft Zr, the said change-shaft being operatively combined withone of the rotating shafts of the loom (herein the cam-shaft (Z) throughmotion-transmitting connections including a clutch. The clutch is underthe operative control of the rod i, and when the said rod is rocked inthe manner which has already been explained the clutch is caused toserve in the transmission of driving power to the change-shaft, wherebythe latter is rotated. The character, arrangement, &c., of themotion-transmitting connections and clutch may vary in practice as preferred or found necessary. In the present case, reference being had toFigs. 1, 2, and 3, the driving arrangements comprise a sprocketwheel d,fast on the cam-shaft (Z, a sprocketchain (Z passing around the saidsprocketwheel (Z and also around a large sprocket-wheel (Z which ismounted loosely upon the changeshaft hand the clutch aforesaid, thelatter serving to couple the said sprocket-wheel (Z to the change-shaftwhen required. The clutch proper is in the present instance similar tothat of United States Letters Patent N 0. 652,105, granted to me June19, 1900. It comprises, essentially, a toothed wheel (P, fast with thehub or sleeve of the sprocket-wheel (Z a dog 71:, pivoted at k upon anarm l? of change-shaft l0, and a spring N, Fig. 2, acting upon said dogwith a tendency to move the latter so as to carry its hooked or toothedend into position to become engaged by one of the teeth of the wheel (Z.The clutch-controlling means is similar in the main to that of the saidLetters Patent N 0. 652,105 and comprises the rod 2" aforesaid, an arm'5 a rod 2* joined to the said arm, and a clutch disengager orcontroller 2, to which said rod is joined also, the said clutchdisengager or controller being mounted to swing upon a vertical pivot mand pose of effecting a weft replenishment.

having an acting portion #yVhICh last is Yer tically ad ustable by meansof a set-screw a.

the dog out of engagement with toothed wheel cl. WVhile it thus acts thechangeshaft is stands at rest, it being held from accidental shift bymeans of the detent-lever 7c, Figs. 1 and 3, the latter having connectedtherewith the spring ls the said spring acting to hold the roll that iscarried by the working end of the detent-lever pressed into anindentation which is formed in the periphery of the detent-disk fast onthe change-shaft. When rod 7; is rockedas, for instance, under the,control of the weft-indicator devicesmotion is transmitted to the clutchdisengager or controller, so as to move the acting portion 1:" thereofaway from the tail of dog 70,

thereby enabling the spring k to throw the dog into engagement with therotating clutchwheel d, whereby the change-shaft is set in rotation andthe replenishment of the working weft-supply is effectuated through theoperation of the instrumentalities which are provided for the purpose.

In order to facilitate the application of automatic weft-replenishinginstrumentalities to looms which have already-been built and to enablesuch application to be efl'ected with a minimum of altering and fitting,I have provided amounting for the above-described changeshaft and itsimmediate appurtenances, said mounting being in the form of a separatestand or stands constructed to support the change-shaft and the movableparts or levers appurtenant thereto and adapted to be secured to thefloor immediately beneath or adjacent a loom. In Figs. 1, 2, and 3 ofthe drawings, m is afloor-stand which is constructed and adapted as hasjust been stated. The said floor-stand is provided at m m with bearingsfor the change-shaft 7a and has attached thereto a bracket of, Figs. 1and 2, provided with a pin or pivot m upon which the detentlever 7c ismounted. The floor-stand-also has attached thereto a vertical pin orpivot 122*, Fig. 3, to which the clutch disengager or controller isapplied, as shown best in Fig. 3. At m m are upwardly-extending lugsuponthe floor-stand m, to which lugs is applied the fulcrum or supportingrod on of the levers, hereinafter referred to, which are operated by thecams on the change-shaft for the pur- The use of the floor-standmrenders it unnecessary to attach bearings, brackets, and the like tothe loomframe for the support of the change-shaft and its more immediateappurtenances and enables said parts to be conveniently applied to loomswhich have already .been built without interference with the usualpartsof such looms as such usual parts are at present constructed andarranged.

For the purpose of afiording time for permitting the weft-replenishingto be effected without undue precipitateness and violence I preferably,although not necessarily in all embodiments of the invention, providemeans for suspending the picking for a predeter' mined number ofmovements of the lay. The

suspension of the picking may be brought tion in its more complete formI have devised the mode of enabling the picking to be suspended, which Iwill now describe. Having reference to Figs. 1, 2, 20, and 21 in theconstruction which is represented in such figures, the arm g with whichthe lug-strap g is connected, is not rigid with the picking rockshaft 9as customary, but is pivotally connected at 9 to a block 9, which blockin turn is' mounted upon a pin or pivot 9 projecting outwardly from thepicking rock-shaft. The block 47 is capable of turning or swingingaround the pin or pivot g in unison with the arm 9 in a direction fromfront to rear of the loom, while the arm 9 is capable of swinging in adirection transversely of the loom upon the pivots which connect thesame with the block g An arm g bolted to the picking rock-shaft g isformed with an extension projecting outwardly from the loom end framea,the said extension having a recess at g, which is adapted to receive thearm 9 the said. arm being caused to occupy the said recess normally bymeans of a tension-spring g, which is connected with the arm 9 and alsowith a fixed portion of the loom-frame. During the regular working ofthe loom the arms Q31 and move in unison, and thereby the picking iseffected. When it is desired to suspend the picking at the change end ofthe loom, the arm g is carried rearwardly out of the recess of thelateral extensiong of the arm 9 of the pick ing rock-shaft g Thereby thearm 9 is uncoupled from the actuating-arm and is not compelled toparticipate in the movements of the latter. For the purpose of drawingthe arm 9 rearwardly automatically the said arm is joined by a strap'orother connection 1 to a lever g which lever is fulcrumed on the rod onand actuated by means of a cam 1 on the change-shaft 70. When the saidcam acts to move the lever the arm 9 and block g are swung rearwardlyaround the pivot or supporting pin g with which the picking rock-shaft gisprovided. When the cam permits the spring to swing the arm g forwardlyagain, it reenters the recess g in the lateral extension Q32 of thefixed arm g on the picking rock-shaft The pickerstick-retracting deviceat g, Figs. 1 and 2,

acts with a tendency to hold the picker-stick g in its outer position,as shown in Fig. 2.

In order to permit the picker-stick to remain in this position while thearms and are uncoupled from each other, the arm g is pivoted, as at tothe block r7 thereby enabling the arm g and block to swivel relativelyto each other, (the arm standing at rest,)whi1e the block participatesin the rocking movement of the picking rock-shaft that is occasioned bythe action of the picking-tappet g.

In the present case the reserve supply of weft or filling is containedin a hopper or magazine at 02, mounted upon the breast-beam,

a supporting-bracket being shown at a attached to the breast-beam (L2and carrying the magazine a.

For the purpose of making the transfer of the reserve weft or fillingfrom the magazine a to the lay an injector or pusher 0 is provided, itbeing mounted upon an arm 0, which is pivoted to the loom-frame at Thesaid arm 0 is joined by a connection 0 with a lever 0*, the said leverbeing pivoted on the fulcrum-rod m and actuated by means of a cam 0 onthe change-shaft h. hen the cam 0 acts to move the lever 0* for thepurpose of carrying weft or filling to the lay, it draws the arm 0 andinjector 0 rearwardly to meet the lay. The arm and injector gravitateforwardly to their normal position again when permitted so to do by theaction of the said cam. The arm 0 is provided with an adjustablecontact-piece o to strike against a stop, as at 0 on the lay when thearm 0 and injector or pusher are moved rearwardly. For the purpose ofenabling the arm 0 and injector or pusher to be moved rearwardly underthe action of the cam until the contactpiece 0 encounters the stop 0 andof thereafter holding the said contact-piece pressed against the saidstop while the arm and injector or pusher participate in the movement ofthe lay the connection 0 is made yielding and elastic. Thus in thepresent case the said connection 0 comprises a rod 0 which is pivoted tothe arm 0 at 0 a similar rod 0 which is pivoted to the lever 0" at 0opposite blocks o o having holes therethrough through which the pair ofrods and 0 is passed, the said blocks having clampingscrews 0 0 by meansof which one of the same is made fast to the rod 0 while the other ismade fast to the rod 0 and a compression-spring 0 surrounding the rod 0between the opposite blocks 0 0 I have shown the magazine a filled orcharged with filling-cases 1). Suitable means is provided for regulatingthe feed of the filling-cases to the injector or pusher 0. Variouscontrivances may be employed for the purpose. I have herein representeda plate a, which is hung pivotally at n to the front of the magazine aand provided with a rear-, wardly-projectinglip at, Fig. 1. A spring, asof, acts upon the plate a and tends to hold filling-case supports, as 00.

the same pressed rearwardly into a position in which its lip a extendsbeneath the bottom filling-case in the magazine 22. and supports thesame, together with the other filling-cases, on top thereof. For thepurpose of moving the plate a so as to withdraw the lip 72. and permitof the descent of the filling-cases which are held back thereby theplate a is furnished with a projection of, extending into the path ofmovement of the injector or pusher 0. As the injector or pusher movesforward into its position of rest it encounters the projection M andpresses the plate a forward, thus withdrawing the lip a, so as to permitthe filling-cases to descend within the magazine n until the bottom onecomes to rest upon The said filling-case supports 0 0 preferably arearranged to move in unison with the said injector or pusher and extendrearwardly thereof, as in Figs. 1, 2, and 3, or may be attached to thelay and extend forwardly therefrom, as in Fig. 24:, Sheet 9. When, now,the injector or pusher is moved rearwardly for the purpose oftransferring the bottom filling-case from the filling-case supports 0 0to the lay, the plate a is released to the action of its spring a, andthe lip 11 thereof is thereby caused to pass beneath the nextfilling-case and support the same above the top of the injector orpusher 0 while the latter is in its rearward position.

When the filling-case supports 0 0 are arranged to move in unison withthe injectoror pusher, the retraction of the injector or pusherforwardly into its normal or inoperative position after having beenmoved rearwardly to carry a filling-case toward the lay also carries thefilling-case supports forwardly out of immediate proximity to thelay-beam. Should the said filling-case have failed for any reason toenter the shuttle in the shuttle-box, this retraction of thefilling-case supports 0 a will permit the same to drop from thelay-beam. Thereby is obviated possible injury, such as might beoccasioned in the advance of the lay by collision of said filling-caseagainst the next reserve filling-case or other objectsin the loom orfrom said next reserve filling-case being carried rearwardly by asucceeding movement of the injector or pusher against a fillingcaselying at the front of the shuttle-box. In Figs. 1, 2, and 3 thefilling-case supports 0 a are constituted by short rods fitted tobearings, as 0 0*, carried by the injector or pusher 0, and are capableof endwise movement through said bearings being kept from endwisemovement by their frictional contact within the bearings. When theinjector or pusher is moved rearwardly, the filling-case supports movein unison therewith until the rear ends of the said filling-casesupports make contact with the lay-beam, after which the injector orpusher moves relatively to the said supports. In the return of theinjector or pusher to its forward position the fillingcase supports moveforward therewith until their forward ends encounter a fixed stop orstops, as at 0 which arrests them inproper position beneath the magazine12; but the injector or pusher continues until it reaches its completelyretracted position.

One of the filling-cases p is shown in detail in Figs. 9, 10, and 11,Sheet 4:, and the form of shuttle which is employed in connection withfilling-cases like that which is represented in the said figures isshown in detail in Figs. 4 to 8, inclusive, same sheet. The body of theshuttle q, Figs. 4: and 5, is formed with an opening q of asize tocontaina filling-case 1), Figs. 9 and 10, the said opening extendingentirely through the shuttle-body, as indicated in Figs. 4, 5', and 6,so asto enable a filling-case to be introduced at one side of theshuttle into the chamber which is constituted by such opening andsubsequently to be expelled at the opposite side. WVhen in positionwithin the opening or chamber g, the filling-case p is retained in placetherein by detents. which in the present instance are constituted byV-shaped blocks (1 Figs. Lto 8, that enter correspondinglyshaped notchesp 79, Fig. 10, in the ends of the filling-case The said blocks arefitted within the vertical slots 1 q of plugs q*, (see more especiallyFigs. 7 and 8.) which are inserted into the shuttle-body at the oppositeends of the opening or chamber (1. The blocks are held projectednormally into position to engage with the ends of the filling-case bymeans of spiral springs 11 11 The said springs surround the stems q q ofthe blocks 9 Q2 and are confined within the longitudinal chambers Q7 gof the said plugs between the blocks and the inner ends of the chambers.When a filling-case is first pressed into the opening or chamber q ofthe sh uttle,the blocks g Q2 yield to the pressure of the end portionsof the filling-case against their oblique faces, so as to permit thesaid filling-case to be forced into position within the opening orchamber q; but when said blocks have been caused by the springs g g toenter the nothes p p of the ends of the filling-case they serve to holdthe filling-case in place during the movements of the shut- ,tle. Theyyield and recede also to allow the spent or failed filling-case to beexpelled from said chamber in advance of the reserve filling-case whichis being substituted therefor when the latter is pressed laterallyagainst the former by the injector or pusher 0 as the said ends of saidends are also beveled off, as attrance to the chamber of the shuttleshould not register properly with each other. In particular the bevels pp at opposite ends of the filling-case and the beveled shoulders g g ofthe shuttle-body at opposite ends of the chamber q are important,inasmuch as they enable a filling-case to enter the chamber q readilynotwithstanding considerable misplacement of the shuttle longitudinallyrelative to the entering filling-case. This misplacement is due to thefact that the shuttle will not always stop at the same point in thelength of a shuttle-box at the ends of its successive flights across theloom. At different times it will vary more or less in the position inwhich it comes to rest within the shuttlebox; The beveled surfaces'p pand (1 q coacting with one another will cause the en tering filling-caseto adjust itself automatically and to properly find the entrance to thechamber (1', even though the shuttle may be misplaced considerably fromits proper posi-.

tionthat is to say, the filling-case resting on the filling-casesupports 0 0 and pressed rearwardly by the injector or pusher 0 is freeto shift end wise relative to the injector or pusher as the inclinedsurfaces p p and q act against one another.

The weft or filling in wound form, which is carried by the filling-case.is contained within the chamber or cavity 19 of the filling-case. Themanner of applying the said weft or filling to the filling-case andretaining it in place therein is not material to the invention. In thepresent instance the filling-case is adapted to receive weft or fillingwound upon bobbins, a bobbin p being shown in position in thefilling-case in Fig. 10, and for the purpose of holding the bobbin inplace within the chamber 19 the filling-case p is provided with a U-shaped clasp p to receive and engage with the head of the bobbin. Themeans of holding the bobbin in place within the filling-case is notmaterial to the invention. At 729 Figs. 9 andlO, is shown theyarn-delivery eye or educt of the filling-case.

The position of a reserve filling-case as it rests upon the fillingcasesupports 0 0 pre- The ends of the yarns leading from the yarndeliveryeyes p of the respective filling-cases within the magazine 02 are inpractice attached to a suitable holder, which may be constituted by apin, as if, Figs. 1 and 2, upon any suitable part in connection with theloom, the said pin being shown herein upon the magazine a. In order thatafter a fillingcase has been transferred from the magazine 01 to theshuttle on the lay the portion of weft which extends from thefilling-case just introduced into the shuttle to the holder n may escapefrom the shuttle-box as the shuttleis picked, the front f of theshuttle-box is so contrived and mounted as to leave a passage 'f Fig. 1,between its lower edge and the upper surface of the lay-beam a Throughthis passage the said portion of weft finds its way when the shuttle ispicked toward the other side of the loom. This passagef need be providedonly at the inner end of the shuttle-box frontthat is to say, at the endthereof next adjacent the warp-although in the drawings I have shownsuch a passage at the outer end of the shuttle-box also. The saidshuttle-box front is attached to arms a 6', extending forwardly from theshuttle-box back 6.

The shuttle-box backehas an opening therethrough, the curved ends ofwhich are indicated in dotted lines at e e Fig. 3, to permit of thepassage of the spent or failed fillingcase as the latter is forced outof the shuttle by the fresh filling-case in process of being introducedinto the shuttle by the injector or pusher 0. p

A filling-case in being introduced into the shuttle by the action of thereplenishing instrumentalities may in some manner be improperlypositioned in the shuttle, so that it projects more or less at the rearside of the latter. For the purpose of insuring that the filling-caseshall not thus project when the shuttle is picked and of properlypositioning a filling-case which has been improperly positioned in beingintroduced by the action of the injector or pusherI provide afilling-casepositioning device, which herein is constituted by a rocker,the said rocker being journaled in bearings at .s" at the rear of theshuttle-box and having a wing or wings s 8 adapted to make contact withthe rear side of a filling-case occupying the chamber q of the shuttlein the said shuttle-box. The fillingcase-positioning device is placedunder the operative control of the change-shaft through connections,which in the present instance comprise an arm s on the said rocker, arod 5 joined to the said arm 8 and a lever 8 to which the said rod 8 isalso joined, the said lever being mounted upon the supporting-rod m andengaging with the cam s on the change-shaft. The said cam is shownseparately in Fig. 13, Sheet 1. Under the control of the portion 8" ofthe said cam the rocker moves so as to press its wing or wings a fortherearward movement of the spent or failed" fillingcase after beingejected from the shuttle. The rocker is moved into this position -bymeans of a tension-spring a, connected with the rod .5" and with thelay-beam. respectively.

In order to avoid injury in case the movement of the positioning deviceis obstructed, a yielding member, as s, is introduced into the train ofoperative connections. This yielding member, herein constituted by acompressionspring, yields to the continued movement of lever 8 when thepositioning device is prevented from completing its forward movement,and thereby obviates straining or breaking of the parts. The use ofthisyielding memher also renders unnecessary delicate adjustment of theparts in order to secure accurate working of the positioner. The extremeforward position of the positioner is determined by means of a stop 8Fig. 12, against which one 01' both of the wings 8 makes contact. Aftersuch contact occurs in the forward movement of the said Wings the springat 8' yields to any remaining portion of the continued movement of thelever 8 The cam s,

by means of which the positioner is operated,

is formed with a portion, as a, by means of which the positioner iscaused to assume at the time of the expulsion of a filling-case from theshuttle in the shuttle-box at the change end of the lay an intermediateposition in the path of the said filling-case. Thereby the saidiilling-case is arrested as soon as it has cleared the shuttle. By thismeans not only is the expelled filling-case prevented from being driventoo violently away from the shuttle, but the said filling-case isarrested in a position to cause it to serve as a stop by means of whichthe entering filling-case is prevented from being driven too far throughthe shuttle-body at either or both ends of the filling-case by theaction of the injector. I thereby provide against either lateralmisplacement of the filling-case in its entirety within the chamber orcavity of the shuttlebody or the projection of either of the ends of thefilling-case at the rear side of the sh uttlebody. The portion a of thecam 8 permits the positioner to assume its entirely-retracted position,in which latter the wing or wings s are withdrawn from the path of theexpelled filling-case. The latter rests upon the supporting-guides 0,Figs. 1 and 14, projecting from the lay at the rear of the shuttle-box,and after the withdrawalof the wing or wings s the said filling-case iscaused by the movement of the lay to pass rearward along the saidsupporting-guides and from the same onto the shelf a), which is suitablyattached to IIO the loom-frame. porting-guides o work in slots o o insaid shelf, as shown best in Fig. 14.

At the front of the shuttle-box at the change end of the loom the edgeof the lay-beam isrounded off, as at Z), Fig. 12, Sheet 1, in order tofacilitate the transfer of a filling of a filling-case from'the magazinea to the shuttlebox and prevent the lower portion of the filling-casefrom catching against the edge of the lay-beam. Therounding off at thisplace also facilitates the dropping of a filling-case which has beentransferred to the lay but for any reason has been prevented fromentering the chamber or cavity of the shuttle on the Pay.

It may sometimes happen that a filling-case after being introduced intothe chamber or cavity of the shuttle in the shuttle-box at the changeend of the loom may project more or less at either the front or the backof the shuttle at one end of the filling-case. For the purpose ofinsuring that a filling-case which thus projects shall be restored intoproper working position in the shuttle I bevel the shuttle-box front andshuttle-box back at the ends of the openings therethrough, as at f f e eFig. 3, so as to form inclined surfaces which by their action againstprojecting portions of the filling-case will operate to force thefilling-case in, so that its sides shall lie flush with the sides of theshuttle-body.

I mount the swell or binder t above the top of the shuttle-box on ahorizontal pivot t",

Figs. 1 and 24, so that it swings in a vertical plane and bears againstthe upper side of the shuttle. A protector-lever t is pivoted at t upona bracket t*,projecting rearwardly from the lay. The forwardly-extendingarm of the protector-lever rests upon the topof the swell or hinder t,and the rear arm thereof is connected, by means of a rod t ,'with therearwardly-extending. arm t of the protector-shaft t the latter beingprovided with the usual dagger t", Fig. 2.

For the convenience of the weaver a container or receptacle, as a, Fig.1, may belocated adjacent the loom to hold a quantity of filledfilling-cases and from which the magazine 72 may be charged by theweaver when necessary, or the said container or receptacle may holdwound filling 1n readiness to be introduced by the weaver into emptyfillingis a deficiency in the supply of reserve filling I provide adetector w, Figs. 1, 2, 3,'and Figs.

15 and 16-, Sheet 5, which acts in connection with the contents of themagazine, and with the said detector I operatively combine knocking-olfdevices and other coacting parts by means of which the driving power ofthe loom is unshipped when the detector indicates de- The rear ends ofthe supficiency of reserve filling in the magazine.

Preferably I arrange so that the devices just referred to shall act tostop the loom before the last charge of reserve filling has beentransferred to the lay, and to this end I arrange the detector so thatit shall be controlledby the reserve charge of filling next succeedingthe one which is in readiness to be fed to the lay by the injector.Reference will now be had more particularly to Figs. 15 to 19, Sheets 5and 6. In these figures the detector 10 is shown in the shape of an armmounted upon a rock-shaft 1/), supported in bearings 102 10 from thebreast-beam a The said arm is shaped so as to extend upwardly from therock-shaft 20, then forwardly over the breastbeam, then outwardly towardthe end of the breast-beam, and then rearwardly, so as to enter anopening at the front of the magazine a, the end of the said detectorbeing adapted to take bearing against the filling-case which is nextabove the filling-case resting on the supports of the injector 0. (SeeFigs. 15 and '16.) The rock-shaft w is acted upon by a light spring 20Fig. 17, tending to move the detector w rearward] y. Thereby thedetector is pressed against the filling-case that is in line with itsend, as in Fig. 16, and when there is no filling-case in line with thesaid end, which will occur when the last filling-case in the magazinehas descended onto the supports 0 0 the spring causes the detector tomove rearwardly into the position which it occupies in Fig. 18.

For the purpose ofbringing about the unshipping of the driving power anarm 10*, Figs. 15, 17, and '19, is attached to the rock-shaft M at thedriving end of the loom. This arm extends upwardly beneath a hunter 20",which is pivoted at w to the inner end of the knocking-off lever 10 thelatter being pivoted at 208 at theouter end of the usual bracket w forthe shipper-handle 10 Normally-that is to say, when the feeler w is heldforward by a filling-case inline with its end, as in Fig. 16 the arm 20*takes a position in which it sustains the hunter Q above the path ofmotion of a suitable going part. In the present case the lay-beam Z)carries a striker Figs. 17 and 19, that is adapted to cooperate with thesaid hunter 1.0 When by the absence of a filling-case p from in linewith the end of the detector w the said detector is permitted to moverearwardly into the position which it occupies in Fig. 18, the arm 20*also moves rearwardly, (see Fig. 19,) lowering the hunter 20 into thepath of motion of the strikerw.

In the next succeeding advance of the lay the the picking rock-shaft gis provided with picking-arm g of usual character rigid therewith andhaving the inner extremity of the lug-strap g connected thereto in usualmanner. The outer extremity of the said lugstrap is connected with thearm g, the latter being pivoted at upon a lever with capacity to swingin a direction from front to rear in the loom. The lever g' in turn ispivoted at 9 upon the support 5 upon which the rocker g of thepicker-stick g is mounted. Lever g is arranged to swing transversely ofthe loom upon the pivot g. Arm g is provided with a shoulder at g totake behind the outer side or edge of the pickerstick g, as shown in.Fig. 22, and from an outward extension or horn g, which when the saidarm g is disengaged from the pickerstick bears against the rear side ofthe pickerstick g and guides the arm g in its movements, so as tofacilitate the subsequent reengagement of the said arm with thepickerstick. This horn g corresponds with the similar outward extensionof the portion of the arm of the picking rock-shaft which is shown inFigs. 20 and 21. The arm g is connected by the strap g with the lever 7operated by cam on the changeshaft k, and when by the action of the saidcam the lever is moved so as to draw the arm ,r rearwardly away from thepicker-stick into the position in which it is shown in Fig. 23 the armis disconnected from the pickerstick. If now the picking rock-shaft isoscillated by the action of the picking-tappet the parts g and g willturn in unison upon the pivot at g, but without operating thepicker-stick. A spring 9 serves to carry the arm g toward the front ofthe loom again when permitted so to do by the cam and when this springis permitted thus to act the shoulder 9 passes forward outside the outeredge of the picker-stick g after the parts g and 9' have been swungoutwardly by the action of the picker-stick-retracting spring g.
